Steppe vegetation the lokality of the Baskunchak lake

The paper presents the results of studies of the steppe vegetation the lokality Baskunchak Lake (Astrakhan region). Based on the use of the floristic approach to the classification of vegetation are selected new associations Agropyro desertori-Stipetum lessingianae ass. nov. hoc loco, Anabasio aphyllae-Stipetum lessingianae ass. nov. hoc loco, Stipo capillatae-Agropyretum desertori ass. nov. hoc loco and new subassociations Stipo capillatae-Agropyretum desertori typicum subass. nov. hoc loco, Stipo capillatae-Agropyretum desertori stipetosum lessingianae subass. nov. hoc loco, Stipo capillatae-Agropyretum desertori alyssetosum turkestanici subass. nov. hoc loco and Stipo capillatae-Agropyretum desertori caricetosum colchicae subass. nov. hoc loco. Their diagnostic types and nomenclature types are given, the composition and structure, ecology and distribution of communities are characterized. The established syntaxons are assigned to the class Festuco-Brometea Br.-Bl. et Tx. ex Soó 1947, order Tanaceto achilleifolii-Stipetalia lessingianae Lysenko et Mucina in Mucina 2016, alliance Tanaceto achilleifolii-Stipion lessingianae Lysenko et Mucina in Mucina 2016.
